- Aurora activity visible from NE Scotland on the evening of 2023-01-13   - Scandinavia magnetometers indicate activity at 19:00 to 01:30 UT with a very strong peak of activity at 22:00 to 00:00 UT   - Activity visible was from observatory at 19:30 to 00:30 UT with a further spell of activity at around 01:15 UT. Main peaks of activity occurred at 21:48 to 22:14 UT, 22:20  to 22:48 UT, and 23:05 to 23:45 UT. The later peak was marked by tall rays up to 25° altitude. Cloud interferred with observations from 23:00 onwards.      - Telescope Images from 2023-01-13 >>

Pictures

Panoramic View - Northern Sky Note on Dew Dew in the interior of AllSky Camera Hemisphere is visible in images above 20-22° altitude but doesn't affect observations of aurora below this altitude.

2023-01-13 22:54 UT Activity beginning to partially hidden by cloud. Faint rays are evident to 25° altitude.

2023-01-13 23:09 UT Cloud partially covering aurora activity , but bright rays in NNW sky to 20° altitude (top of rays hidden by dew on interiror of camera's hemisphere)

2023-01-13 23:13 UT Aurora arc faded and partially hidden. Rays in NW Sky to at least 20° altitude.

2023-01-13 23:25 UT Aurora activity behind foreground clouds. Rays to around 15-18° altitude

2023-01-13 23:35 UT . Aurora activity still present (but partially hidden). Bright ray in NNW sky

2023-01-14 00:02 UT Aurora activity still present, but increasing hidden/dimmed by cloud.

Magnetometer Stack Plots (for reference)

Magnetometer Stack Plots from Scandinavia (ordered by latitude) H Component - 2023-01-13 / 2023-01-14 Original data from Tromsø Geophysical Observatory (TGO), DTU Space (Technical University of Denmark) and Finnish Meteorological Institute (FMI, displayed on SpaceWeatherLive http://www.spaceweatherlive.com/en/auroral-activity/magnetometers). Note: Geomagnetometer activity at rvk (Rorvik, 64.95N), dob (Dombas, 62.07N), sol (Solund, 61.08N) and kar (Karmoy, 59.21N) stations are used as indicators for potential auroral activity that may be visible from my Observatory situated at latitude 57.32N  (Map of Stations)
